NDLI: Reliability enhancement of a steep slope tunnel transistor based ring oscillator designs with circuit interaction

Abstract	Tunnel field effect transistors (TFETs) have emerged as one of the most promising post-CMOS technologies for digital, analogue and RF designs. However, it has been demonstrated by several researchers that TFET circuits face increased on-state Miller capacitance effect, which leads to poor transient characteristics with large overshoots and undershoots. This would minimise the reliability of TFET circuits though energy efficient. This work gives more design insights (optimal sizing, number of stages, supply voltage) into TFET circuit reliability and proposes a TFET based circuit interaction design approach for ultra-low power and reliable ring oscillator circuit design. It has been shown that TFET circuit designs without proper reliability enhancement techniques such as circuit interaction or co-design approach exhibits very large undershoots/overshoots (∼20–50%). The proposed TFET circuit co-design approach (i.e. differential topology based design in comparison with the complementary static TFET logic designs) enhances the TFET circuit reliability by minimising the undershoots/overshoots to less than 0.5% with a trade-off in operating frequency and power consumption.
